// USAGE
// 1. Adjust the database configuration and charset in this file
// 2. Remove the old tables on the target database if your dump doesn't contain "DROP TABLE"
// 3. Create the working directory (e.g. dump) on your web server
// 4. Upload bigdump.php and your dump files (.sql, .gz) via FTP to the working directory
// 5. Run the bigdump.php from your browser via URL like http://www.yourdomain.com/dump/bigdump.php
// 6. BigDump can start the next import session automatically if you enable the JavaScript
// 7. Wait for the script to finish, do not close the browser window
// 8. IMPORTANT: Remove bigdump.php and your dump files from the web server
// If Timeout errors still occure you may need to adjust the $linepersession setting in this file
// LAST CHANGES
// *** First ideas about adding plugin interface
// *** Fix // delimiter bug
// *** Minor fix to avoid Undefined variable curfilename notice
// *** Handle empty delimiter setting
// *** New way to determine the upload directory
// *** Set UTF8 as default connection charset
